How do I get rid of an unwrap?

So, I unwrapped an object yesterday and I was kind of lazy about it, (it’s a hand and I should have done the nails separately but I kind of just went “Meh.”) and now I want to redo them and do it properly this time, but how do I cancel the old unwrap I did on them?

You can either just U -> unwrap and start again, or F9 and remove the UV Texture on the Mesh panel.

When you press U there is a reset opion

So there is, nice one…
